FUMIGA'TOR.

PECIPICATION forming part of Letters Patent No. 39 dated NOvembeI 1888- Application filed February 18, 1888. Serial No. 264,507. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID L. SNEDIKER, of Emporia, in the county of Lyon and State of Kansas, have invented certain new and useful Improvements in Fumigators or Insect-Destroyers, of which the following is a specification, reference being had to theaccompanying drawings.

The object of my invention is to provide slmple and convenient appliances in connection with a hand-bellows for producing and delivering sulphur fumes, or the fumes of any other suitable substance for destroying insects; and my invention consists in the combination of parts hereinafter described and succinctly specified in my appended claims.

In the drawings, Figure 1 is a central vertical section on the line 1 1 of Fig. 2 of an ordinary hand-bellows with my improvements applied to it. Fig. 2 is a section of thesame on the line 2 2 of Fig. 1, the nozzle of the bellows being shown in elevation. Fig. 3 is a vertical central section, on a larger scale, of the heater-case detached from the bellows. Fig. 4. is a vertical section, also on a larger scale, of the receptacle for sulphur detached. Fig. 5 is a cap-nut adapted to close the opening in the bellows when the sulphur-receptacle is removed. Fig. 6 is a larger cap-nut adapted to close the opening in the bottom of the bellows when the heater-case is removed.

Referring to the letters upon the drawings, A indicates a hand-bellows; B, its nozzle; 0, its air-supply valve, and D its check-valve, to prevent air from being drawn into the bellows through the nozzle.

E indicates a cylindrical form of heater-case, which is probably the most convenient form, screw-threaded near its base at F, and adapted to screw into the bottom of the bellows-frame, as shown in Fig. 1. This cylinder contains a fire-box or receptacle, G, for any suitable combustiblesubstance-such as alump of charcoal, for example. This fire-box is the fumigator of the apparatus, andisperforated,asindicated,on its sides and open at its top to hold sulphur or other substance to be heated and converted into fumes. It may be supported in any suitable manneras, for example,by a standard,l.

K indicates an opening in the side of the cylinder in a line with theoutgoing current of air.

L indicates blocks of metal, forming a wall around the heatercase, thereby forming a noncombustible chamber, X, and the perforations in the sides of the fire-box.

M indicates a sulphur-receptacle on the upper side of the bellows, tapering at its bottom and provided with an adjustable feed-valve, which maybe in the form of a cone, N, secured to a rod, 0, screw-threaded at P, and passing through the coverQ of the sulphur-receptacle. The bottom of the receptacle being conical,the valve may be adjusted by means of this screw up and down, to fit more or less closely into the opening in the bottom of the sulphur-receptacle, to regulate the feed, as desired.

R indicates a chute leading from the bottom of the sulphur-receptacle,and inclined so as to gradually deliver the sulphurinto the fire-box. It also permits the sulphurreceptacle to be further removed from the source of heat. The sulphur-receptacle may be screwed into the top of the bellows, so that when the bellows is not desired to be used for fumigating purposes the receptacle can be removed and the bellows will serve for ordinary uses.

The heater-case containing the fire-box may also be removed, and suitable screw-plugs may be provided to screw into the threaded openings of the upper and lower parts of the bellows, as shown in Figs. 5 and 6. All the detachable parts can be manufactured in quantities of suitable sizes, so that when any part is lost or injured it can be supplied at little expense, and thus the bellows can be kept in order constantly for all purposes.

By my improved construct-ion I get the firebox and the substance immediately being converted into fumes all within the bellows and in the path of the current of air passing out of the nozzle in the usual way.

The fire-box or fumigator might be used without the heater-case; butI prefer to use both together, because the latter is a protector.

It will be seen from the construction and arrangement of the parts that the air is forced over the top of the heater-case, thence down wardly through the fire-box and out through the nozzle, carrying the fumes from the firebox with it. The cap of the sulphur-receptacle should fit tightly enough to prevent the air and fumes from escaping out through the receptacle.

What I claim to be new, and desire to secure by Letters Patent, is-

1. A hand-bellows provided with a non-combustible chamber, X, between the bellows and its nozzle, and a removable fire-box or fumigator within the chamber, substantially as set forth.

2. The combination, with a bellows and no zle, ol'a noncombustible chamber commuuieating between the two, containing a heatercase provided with an air-opening in its side, and adapted to lit in place in the chamber X, and the perforated lire-box within the heaterease, substantially as set forth.

3. The combination, with the bellows provided with a non-combustible chamber, X, and a firebox within the same, of a receptacle at- DAVID L. SNEDIKEIL.
